Fushun City is one of the important and large coal industry bases in China. With long-term excavation operations, the stopes and pits are continuously enlarged and deepened, the ground instability of the mining area and its peripheral areas is aggravated and geological hazards such as localized ground subsidence have already occurred. This brings direct threat to production and living of the local people and seriously influences sustainable social and economic development. In this study the types, quantity and manifestations of existing geologic hazards in the urban study area and the interrelations between geologic hazards and faults were ascertained rapidly by using the remote sensing technique, thus offering an accurate and reliable basis for the prevention and control of geological hazards in the area. The application of the remote sensing technique yielded good results.
